WINDOW-CONTROLLING DEVICE.

Application filed July 1'7, 1920, Serial No. 397,010. Renewed July 6, 1925.

The invention relates particularly to a device for controlling windows of the type generally used in closed cars and provides, among other objects, a device which may be quickly and easily attached, which is concealed with the exception of the operatmg handle, which adapts the'window to be easily adjusted to any desired position and which will automatically latch and unlatch the window upon release and actuation of said handle respectively. p

\Vhile the invention will be fully descrlbed in the following specification I do not wish to be limited to the preferred embodiment shown, as in its broader aspects it is capable of embodiment in numerous forms.

In the drawing: a

Figural is an interior view of a closed vehicle door to plied;

Figures 2 and 3 are a side and top view,

in partial section of the device detached;

Figure is a fragmentary side view showwhich the invention is aping the manner in which the device becomes unlatched upon downward movement of the operating handle.

Describing the invention in detail, A is an automobile door, having in its upper portion a window opening A for which a vertically slidable glass platen forms a closure, the lower portion of said door being hollow as indicated at A and said glass being adapted to enter the chamber A when lowered. Within said chamber is located a controlling device for the sliding glass, constituted as follows C is a bracket member comprising the right angle pieces C and C attached b screws 13 to one of the uprights B of the door. D is a stub shaft journalled in said bracket member and carrying the lifter arm E. a

This lifter armis mounted between the angle pieces C and C and is centrally slotted to permit the installation of a coun tel-balance spring member comprising a plurality of springs F extending from points F at the free end of the lifter arm to acommon'anchorage member G, secured to a pin H positioned above the stub shaft D on said bracket member. These springs are tensioned to urge the lifter arm upwardly with a force substantially counterbalancing the weight of theglass A the oounterbalancing effort being transmitted to the glass by a 'ing teeth C roller I journalled upon the free end of the lifter arm and engaging a metal channel member J secured to the bottom edge of the glass.

An operating and automatic latch mechanism is provided for the device thus far described, as follows:

A rock arm M is pivoted upon a pin L carried by the lifter arm E at one side of the axis of said arm.

Said rock arm M is provided with a short rack of lateral teeth M and with an enlarged portion M slotted as indicated atM to engage the stub shaft D. As is shown in Figures 2 and at, the portion it 2 provides opposed sockets N and N for housing two coiled springs N and N which oppositely abut against the stub shaft D. The function of these springs is to normally maintain the rock arm in the position shown in Figure 2, with the stub shaft equally spaced from the ends of the slot B1 in which position, the teeth M on the quadrant will engage a relatively large rack of oppositely projecton the bracket member C X is a handle attached to the enlarged portion M of the quadrant member by bolts Y, said handle being arranged adjacent the inner face of the door, all other parts being concealed within the chamber A To operate the described device, the handle X is actuated in the direction in which it is desired to shift the glass A Thus, if the handle is moved in a downward direction, as shown in Figure 4, the initial move ment thereof due to the arm M will be independent of the lifter arm E, and will rock about its pivot L to'the position shown in Figure 4, the spring N being compressed during such movement of the rock arm. The angle through which the rock arm swings is determined by the length of the slot M this distance of travel being snflicient to completely disengage the teeth M and C Continued pressure upon the handle X will then swing. the lifter arm E downward to the desired position, the handle then being released and through the medium of the equalizing springs N and N being returned to its neutral or intermediate position automatically.

To move the arm E upward, a similar action of the parts takes place with the exception that the rock arm is swung in an opposite direction so that the spring N is compressed while stub shaft 1) forms an abutment forthe opposite end of, the slot M and the teeth M swing outwardly beyond the teeth C to disengagement. It is to be noted. that the rock ai'ni M forms in effect a latch ineinsaid lost motion.

bers and shifting ofsaid lifting element is effected by a movement of said actuating handle constant in direction.
